ReceptionRating · Positive reviews · Number of ratings

U Game Engine + xLua holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sticky has 8.8K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of Sticky's written reviews are positive against 0% of U Game Engine + xLua's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sticky ships an update every 2 weeks, U Game Engine + xLua fortnightly. The most recent releases landed on October 11, 2026 and October 3, 2026 respectively.
